The Origins of the Neolithic Along the Atlantic Coast of Continental Europe: A Survey

The main aim of this work is to compare the processes of transition to the Neolithic along the Atlantic coasts of continental Europe. Archaeological data on the late Mesolithic and the early Neolithic in the best known regions (central and southern Portugal, Cantabrian Spain, Atlantic France, the shores of the North Sea, and southern Scandinavia) are discussed. The transition to the Neolithic in Atlantic Europe can be viewed as a relatively late phenomenon, with several interesting particularities. Among those, we point out the fundamentally indigenous character of the processes; the existence of a long availability phase, in which hunter-gatherer groups maintained contact with neighboring agriculturalists and probably were familiar with farming and animal husbandry without applying them in a systematic way; and the later development of megalithic monumental funerary architecture. Finally, the main hypotheses so far proposed to explain the change are contrasted with the available evidence: those that argue that the change derives from economic disequilibrium, and those that opt for the development of social inequality as the fundamental cause.     

The Origin of African Sheep: Archaeological and Genetic Perspectives

Indigenous African sheep genetic resources have been classified into two main groups, fat-tailed and thin-tailed sheep. The fat-tailed sheep are the most widely distributed, being found in a large part of North Africa (from Egypt to Algeria) and in Eastern and Southern Africa (from Eritrea to South Africa). The thin-tailed sheep are present mainly in Morocco, Sudan and in West Africa. African sheep were domesticated outside Africa. They share a common ancestry with European and Asian sheep. Archaeological information supports separate introductions and dispersion histories for the African thin-tailed and fat-tailed sheep. The first sheep entered Africa via the Isthmus of Suez and/or the southern Sinai Peninsula, between 7500 and 7000 BP. They were likely of the thin-tailed type. Fat-tailed sheep entered Africa through its northeastern part and the Horn of Africa. Mitochondrial DNA analysis supports a common maternal ancestral origin for all African sheep, while autosomal and Y chromosome DNA analysis indicates a distinct genetic history for African thin-tailed and sub-Saharan fat-tailed sheep. The main ancestral population of southern African fat-tailed sheep likely originated in East Africa. Further work is needed to assess the possible dispersion of sheep from western Africa to the southern African regions.     

Warriors and blacksmiths: Mediating ethnicity in East African spears

Ethnoarchaeology offers some ability to transform contemporary forms of social constitution into a method for interpreting prehistoric social patterns and for understanding the coevolution of symbolic and utilitarian technologies. In north-central Kenya, one social caste of Lokop pastoralist actors (warriors) interacts with another (blacksmiths) to build a technology for socially constituting gender and social age. Three aspects of this process can help to direct analogous archaeological research in prehistoric contexts. First, this case reiterates that symbols for and symbolic acts of gender and social age continually help actors to constitute or negotiate their places within varied social fields. It is clear, however, that the connection between social prestige—essentially the goal of Lokop personal adornment—and real economic or political power is not necessarily direct. For Lokop herders, foreign traits of spear morphology are the stylistic raw material for constituting internally defined social fields. Ethmic distinctions are more pasively constituted, almost as an epiphenomenon. Second, the constituative significance of material symbols may be grasped without appealing to or understanding the cultural meaning of forms (in an emic sense) from only the archaeological evidence. In fact, prehistorians should not concern themselves with attempts to reconstruct the meaning of cultural phenomena. Rather, archaeological inquiry should attempt to infer the meaningfulness of formal traits within a specific social context, based on significant material patterns in the archaeological record. Third, the items of meaning themselves are constituted with their own material means of production, and these systems may be interpreted through economic models more familiar to archaeology. The Lokop case encompasses producers and users both as specialists. Blacksmiths rely on their marginal positions in herding society to make them the brokers of morphological traits. Warriors, also accustomed to marginal status, effectively collaborate with blacksmiths to set up their own future place as elders. For archaeological applications in prehistory, the exchange and processing of raw materials should reconstitute economic hierarchy in a very clear manner.     

Early African America: Archaeological Studies of Significance and Diversity

This article examines archaeological studies of the cultural heritage and social dynamics of African descendant populations in the United States and Canada from AD 1400 through 1865. European colonial enterprises expanded in Africa and the Americas during that time span, effecting an accompanying movement of free and captive Africans into North America. Archaeological investigations of early African America are remarkable for the diversity of analytic scales and research questions pursued. This diversity of research efforts has yielded a highly productive, interdisciplinary expansion of knowledge concerning African diaspora histories.     

非洲农业起源和传播的路线与过程

本文根据非洲大陆不同的地理环境划分出五个区域,分别介绍各区与农业起源相关的考古发现等证据。这五个区域包括:尼罗河流域、撒哈拉沙漠及其以北地区、撒哈拉沙漠以南的热带稀树大草原区、热带雨林边缘地区、埃塞尔比亚和南非高原区。通过相关证据的时间早晚以及作物种类差异分析,梳理出非洲农业起源和传播的路线与过程,进而认为非洲的农业起源是受外来影响所致,但在撒哈拉沙漠以南主要为技术影响,而非直接的作物品种输入方式。     

Avoiding Disaster: Diversification and Risk Management among East African Herders

This article addresses processes of livelihood diversification among pastoralists in the rangelands of northern Kenya and southern Ethiopia. The objectives of the article are threefold: (1) to suggest a theoretical framework for addressing income diversification among pastoralists with reference to current literature and databases; (2) to present a case study on pastoral income diversification based on preliminary field research in northern Kenya and southern Ethiopia; and (3) to summarize current understandings of pastoral diversification while pointing to additional empirical research needs. By showing how comparative analyses in the region have been constrained by theoretical and data deficiencies, the article explores ways in which income diversification differs by what are termed conditional, opportunity, and local response variables. Climate, distance to market towns, gender, wealth, and education are attributes covered by these variables and discussed in the article. The conceptualization and case study provide useful bases for conducting comparative research on pastoral diversification in East Africa specifically, and in sub‐Saharan Africa generally.     

Neolithic Pottery Traditions from the Islands, the Coast and the Interior of East Africa

Scholars have attributed the spread of agriculture and pottery technology to the larger part of eastern and southern Africa to Bantu speakers. However, the spread of similar aspects to the Kenya and Tanzania Rift Valley as far south as Eyasi Basin and as far east as Mount Kilimanjaro has been attributed to Cushitic speakers. Whereas the spread of these innovations to the Rift Valley region can be dated back to 3000 BC, the remaining part of eastern and southern Africa is alleged to have received similar innovations only after the BC/AD changeover, when iron technology was introduced. These theories can no longer be sustained. The coast of Tanzania, its immediate hinterland, and the deep sea islands of Zanzibar and Mafia were settled by people who had knowledge of agriculture and pottery making probably from 3000 BC. These innovations are also found to have spread to southern Africa in the last millennium BC. The introduction of iron technology and beveled/fluted pottery, associated with Bantu speakers, was just another stage in the cultural evolution of the people of eastern and southern Africa, but not the beginning of settled, farming/domesticating communities.La diffusion de l'agriculture et la technologie de poterie à la région plus grande de l'Afrique orientale et méridional ont était attribué au parleurs des langues bantou. Cependant, la diffusion des aspects semblables au Rift Valley de Kenya et Tanzania, sud au Bassin d'Eyasi et est au Mont Kilimanjaro ont était attribué au parleurs des langues Cushitic. Tandis qu'on peut dater la diffusion de ces innovations à la région du Rift Valley à 3000 BC, il est prétendu que la région restante d'Afrique orientale et méridional ont reçu les innovations similaires seulement après le changement de BC/AD, au temps que la technologie de fer était indroduit. Il n'est pas possible maintenant à sustenir ces théories. La côte de Tanzania, son hinterland immédiat/les regions près de la mer, et les îles de Zanzibar et Mafia, ont étaient colonisé par les personnes qui avait la connaissance de l'agriculture et de la poterie probablement à partir de 3000 BC. On peut trouver aussi que ces innovations ont diffusé à l'Afrique méridional pendant la dernier millénaire avant J. -C. L'introduction de la technologie du fer et la poterie avec le biseau, liée avec les parleurs des langues bantoues, était seulement un autre étape dans l'évolution culturelle du peuple de l'Afrique orientale et méridional. Il n'était pas le commencement des communautés établis qui ont pratiqué l'agricole et la domestication.     

Intersections, Networks and the Genesis of Social Complexity on the Nyali Coast of East Africa

This paper examines intersections between different societies occupying the Nyali Coast region of southern Kenya from the late first millennium ad to the mid-second millennium ad. We explore interaction between societies at three scales: between hunter-gatherers and farmers in the coastal hinterland, between the hinterland and the coast and between the coast and the wider Indian Ocean. The patterns indicate that local intersections in the hinterland between hunter-gatherers and farmers went hand-in-hand with both the emergence of larger settlements in the hinterland and on the coast, and participation in a pan-Indian Ocean trade network.     

For Richer,for Poorer: Marriage and Casualized Sex in East African Artisanal Mining Settlements

Migrants to Tanzania's artisanal gold mining sites seek mineral wealth, which is accompanied by high risks of occupational hazards, economic failure, AIDS and social censure from their home communities. Male miners in these settlements compete to attract newly arrived young women who are perceived to be diverting male material support from older women and children's economic survival. This article explores the dynamics of monogamy, polygamy and promiscuity in the context of rapid occupational change. It shows how a wide spectrum of productive and welfare outcomes is generated through sexual experimentation, which calls into question conventional concepts of prostitution, marriage and gender power relations.
